Abstract
The utility model provides corneal foreign body forceps. The forceps comprise forceps handles, crank arms and forceps claws. The forceps are characterized in that an angle of 135 degrees is formed between each of the crank arms and each of the forceps claws, tips of the forceps claws are sharp, and insides of middles of the forceps claws are in a recessed structure. The angle of 135 degrees is formed between each of the crank arms and each of the forceps claws, so that the sight cannot be impeded during foreign body picking, forceps claws with sharp tips can be embedded in the rear of a foreign body, the foreign body can be clamped firmly due to the recessed structure of insides of middles of the forceps claws, and the foreign body is prevented from falling off. The forceps are reasonable and simple in design, rapid and convenient to use, little in corneal damage and high in corneal foreign body extraction success rate.
Description
Technical field
This utility model belongs to the ophthalmic medical instrument field, relates to particularly a kind of corneal foreign body forceps.
Background technology
Corneal foreign body is disease common in the clinical ophthalmology work, the large multiplex foreign body needle of present Therapeutic Method or asepsis injector syringe needle are chosen except corneal foreign body, and when choosing except foreign body, syringe needle is sharper keen, pierce through easily cornea even damage crystalline lens and cause cataract, the secondary intraocular infection.Repeated multiple times choosing except also staying cicatrix at cornea causes corneal leukoma, affects patient's vision and outward appearance.For the foreign body of cornea deep layer, because foreign body embedding cornea is darker, then can't foreign body be chosen with apparatus and remove.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of design of taking out for corneal foreign body specially is provided, and can realize simple and efficient corneal foreign body forceps without injury.
The technical solution of the utility model is: corneal foreign body forceps, by the tweezer handle, crank arm, the tweezer pawl forms, it is characterized in that: described cranking arm is 135 ° of angles with the tweezer pawl, and described tweezer pawl tip is sharp keen, and the inboard, middle part is sunk structure.
Describedly crank arm that to be 135 ° of bendings with the tweezer pawl be unsighted during for fear of the gripping foreign body, most advanced and sophisticated sharp keen tweezer pawl can embed the rear of corneal foreign body, and the sunk structure of inboard, middle part is convenient to firmly clamp foreign body, prevents from coming off.
Advantage of the present utility model and beneficial effect are: this corneal foreign body forceps simplicity of design is reasonable, convenient to use, and the damage of corneal is little, and the success rate that corneal foreign body takes out is high.
